Codebreakers are a fun way to build numeracy skills.
Hominid → hominin → Homo are terms used to classify human ancestors and relatives.
Homo erectus appeared around 2 million years ago. They had modern body proportions, walked fully upright, and were strong long-distance runners.
Homo erectus spread out of Africa into Asia and Europe.
The populations that remained in Africa eventually evolved into Homo sapiens, while groups in Europe evolved into Neanderthals.
Neanderthals appeared first, around 400,000 years ago. Homo sapiens appeared later, around 300,000 years ago.
Around 50,000 years ago, Homo sapiens migrating out of Africa encountered Neanderthals in the Middle East and Europe.
Within roughly 10,000 years, Homo sapiens became the dominant human species in Europe and replaced Neanderthals.
Possible reasons for Homo sapiens succeeding include stronger social cooperation, much larger populations (possibly around 10:1), and faster innovation such as advanced hunting strategies.
People of non-African ancestry today typically carry about 1–4% Neanderthal DNA due to interbreeding.
Fossil skulls can often be distinguished because Homo sapiens are the only human species with a prominent bony chin.
Neanderthals had larger brains on average, were shorter and more heavily built, and likely had exceptional eyesight, while Homo sapiens had more refined cognitive and social abilities.
